Oregon Regulators Say Coffin Butte Landfill Failed for Years to Monitor and Control Gas Emissions Environment By Lucille McNamara On Mar 12, 2026 Last updated Mar 12, 2026 Coffin Butte Landfill, Benton County, Oregon | Credit: Bigcran An enforcement order with a civil penalty exceeding $3 million was issued by the Oregon Department of Environmental Quality (DEQ) yesterday for violations at Coffin Butte Landfill, north of Corvallis. Valley Landfills Failed to Monitor, Capture, or Control Landfill Gas Emissions The enforcement order alleges that Valley Landfills Inc. failed to monitor, capture, and control landfill gas emissions required by both federal and state law. Landfill gas contains hazardous pollutants that are harmful to human health. It consists mostly of methane, a potent greenhouse gas that contributes to climate change and emits odors into the air. DEQ alleges in its $3,016,128 order that $2,265,528 is the economic benefit Valley Landfills gained by: Failing to monitor surface emissions. Failing to install new landfill gas collection wells. Failing to monitor and repair the landfill cover. Tidings Insight DEQ’s economic benefit figure is not just punishment. It reflects the money regulators say the landfill saved by delaying required gas monitoring, repairs, wells, and control work. If Valley Landfills completes multiple corrective actions, DEQ may reduce the civil penalty. The enforcement order is the result of compliance investigations conducted over several years by the U.S. Environmental Protection Agency (EPA) and DEQ. The Public Will be Given an Opportunity to Comment The public will be given the opportunity to comment when DEQ’s Air Quality program considers the renewal of an air permit for Valley landfills this spring.
